When I try running InstallShield in windowed mode ("Desktop" = "640x480" as per default in config), window appears for a second and then dissapears printing this message:
X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 12 (X_ConfigureWindow) Serial number of failed request: 93 Current serial number in output stream: 98
Did latest modifications of x11drv break anything?
