i have a strange problem with my Dialog based application written in VC++6.0
in one of the dialog box (let's call it dialog box A) . it can call some other dialog box that should pops up in front of the dialog box A. (by calling something like dlg.DoModal() or AfxMessageBox ) But SOMETIMES those pop up dialog boxes just doesn't show up (i.e. dialog box A become inactive.. but the pop up dialog box can't be seen until you press the "alt" key). it seems there is something wrong with the dialog box A because even the "afxmessagebox" dialog box won't appears when i have this problem.
not sure if i explained it clearly or not .. Any idea what is causing the problem and how can i fix it?
i was using the same dialog box and code for an earlier version of the software and it was running fine at that time
