Delphi 7 Translucent forms in Windows Terminal Services

Hi,
Our programmers have written a Delphi 7 application that uses Translucent Objects.  On our normal Windows 2000 workstation machines, the translucent objects work fine using 256 colours, however our Windows 2000 Terminal Server machines do not correctly hide the Translucent object when using 256 colours as terminal users.  Why is it different and is there a fix?
Thanks,
Steve

Might be just a driver problem. The client software might not support translucent windows... Terminal clients are a bit limited in their abilities anyway.

I thought that as well, but it works fine in 256 colour mode if I log onto the console of the Terminal Server.  The problem is only evident with Terminal Server sessions.  Do you know of any Delphi doco's that might deal with Terminal Servers?

I'm not too familiar with terminal services. However, this problem is most likely related to the video driver for the terminal session. The video information must be sent from the server to the client and Terminal Server tries to save bandwidth by not sending too much into. Thus, the translucent information is probably trimmed away by the server when it's sent to the client.

Yeah, I expect that this is the case as well - does anyone have any suggestions how to fix this?

Ehm, solution? Don't use translucent windows. :-)
Or don't use terminal services. I've had to get some application working with terminal services once, never found the real solution and had to tell my employer that I could not solve it by myself. (And neither could anyone else.) From that point, I try to avoid terminal services as much as possible...
