Disappearing Command Buttons

Ok heres the situation:

I have a form, with a tabcontrol on it. When the form is started there
are a couple of command buttons on the first screen and the rest of the
tabs in the control are removed so only the first screen is displayed.
On some machines, mainly XP, those buttons are missing... completely
gone, nothing there at all! Clicking around the area does NOT cause
the onclick events to fire. It only happens on some machines and I
cannot work out why! I also have a toolbar on that screen however all
the buttons on that toolbar still work and are NOT missing!

The OS's are the same, all running SP2 the only difference is screen
resolution, which I have changed and still it doesn't work!

Has anyone else had this problem? Or is it just something I have
inadvertantly done?
