X Applications with Incorrect Colors

If your X applications do not display the correct colors, follow these steps to reverse the order that NCD Thin Client Xware allocates color cells:

For Windows NT 4.0, Terminal Server Edition:

Select Start\Program\NCD Thin Client Xware\NCD Thin Client Xware Configuration.
On the General tab, click Advanced Settings.
Select Allocate colormap entries from the top, then click OK.
Click Apply and then OK on the General tab.
Restart your X application.

For Windows NT 3.51:

Select the NCD Xware program group in Program Manager.
Double click Xware Configuration.
On the General tab, click Advanced Settings.
Select Allocate colormap entries from the top, then click OK.
Click Apply and then OK on the General tab.
Restart your X application.

MS Windows Color Palette and X Applications

Some MS Windows applications (MS Excel, for example) redefine the entire Windows color palette. This may cause "color flashing" when changing focus from an X application back to the Windows application.

NCD Thin Client Xware manages color with Windows palette manager. RGB pixel values are preset by Windows, 0 to black and 255 to white, and cannot be changed. X applications that require other color values for 0 and 255 will display colors incorrectly.

X11perf Benchmark Program

This program uses two Kanji/Kana fonts in eight of its tests. These fonts are installed as part of a typical installation of NCD Thin Client Xware.
If you see an error from X11perf similar to this, you need to increase the graphics resolution:
```
X Error of failed request: BadMatch

(invalid parameter attributes)

Major opcode of failed request: 73

(X_GetImage)

Serial number of failed request: 16

Current serial number in output stream: 16
```
X11perf creates a 600 x 600 window with a 1-pixel border, 2 pixels from the edge of the screen. Unless you have a screen taller than 603 pixels, part of the X11perf window is off the screen. This error displays when you try to run it on a smaller screen.

NCD recommends that you run the benchmark on a 1024 x 768 video adapter. Some X servers may misinform the program about screen size. In this case, the performance numbers are inaccurate as they have several pixels missing from the bottom of the window.

Panned Windows May Redraw Incorrectly

In single window mode (NCD Thin Client Xware Configuration\General\ X Applications\Run in a single window), if the Window size is larger than the physical display, X applications that appear partially off screen may not redraw correctly when moved back on screen.

Use IP Address

NCD Thin Client Xware 5.1 enables you to refer to your NT Server by just its IP address. This is useful when your network is not configured with a DNS server or in DHCP or PPP Dialup Router environments, where a NT Server�s name may not match the dynamic address assigned to the NT Server. This feature is also helpful if you experience timeouts because your DNS host is a long distance away. By specifying the IP address, you prevent the DNS host from attempting to obtain the address by scanning all XDM broadcast hosts. See the explanation of the Use IP Address option in the section "Xware Advanced Settings" in the online help or What�s This Help.

X Backgrounds

Because Windows doesn't accept X bitmaps as backgrounds, X applications can't set the screen background on the Windows desktop. This limitation only applies when NCD Thin Client Xware Configuration\General\X Applications is Run on the desktop.

Enabling Windows to See Your Mouse Presses

Windows NT 4.0, Terminal Server Edition - only

Many X window managers, including NCD Thin Client Xware's NCDwm and the Open Look window manager olwm, display a menu when you press a mouse button on the X window desktop. Because Windows displays a menu when the right mouse button is pressed, NCD Thin Client Xware must decide whether you want the X or the Windows menu.
