Martin, you may have an answer to this issue:

I have an VFP8 Exe that Calls an VFP8 APP that display a Menu with command buttons on Sidebar form. Some of those command buttons call other APPs that has FOX2X forms, VFP7 Forms,etc.
The Fox2x Forms command button background color changed from gray to White, also little light gray shading effect around the edges of the command buttons is shown.
The VFP7 forms look Ok.

This color changes show up when Running the EXE under VFP8 or under Citrix Client


Also, When I set Magenta Color for a Shape bacground on the sidebarform, the color change to medium Gray under Citrix Client only but not from VFP8

Thanks,
Jean Haidar
