VB Program not on top

I have a VB program I wrote. Its an "exe" that is kicked offby a macro in SolidWorks.

For years it has run fine, but recently we have started gettingsome computers with Winxp x64. The program works but it doesn'tcome up on top of the SolidWorks window. It blinks in the task bar.Its not minimized as I don't have that option even available to theuser. It just doesn't steal the focus from the SolidWorksapplication....but only on Winxp x64. On regular Winxp it worksfine.SolidworksApi macros
