[XP] some controls are hidden in "Windows Classic Style"

I have a program which uses some dialog boxes. If I use "Windows Classic Style" (Control Panel => Display => Appearance => ' Windows Classic Style' (from the 'Windows and buttons:' drop down list)) and run the programming, some of the controls are not displayed on the dialog box. If I run the same program by selecting "Windows XP Style" then everything is displayed properly. How to run the program and get all the contrls displayed in "Windows Classic Style"? Is there any setting to be done?

Thanks,
Vivek.

I'm sorry, but I don't think that's possible...

Did you try other machines?

Sounds like a program bug to me, tell the author about it.
