Hello, all.
I am having a problem showing a VB6 form modally in AutoCAD 2005, when SDI=0, TASKBAR=1 and there are multiple drawings open. The problem is that the form does not display on the screen: it flashes briefly, then AutoCAD will not respond. If AutoCAD is the only program running, the user can use Alt+Tab to cycle through the AutoCAD windows until he/she reaches the VB6 form. However, if any other program is running, Alt+Tab does not cycle through the AutoCAD windows, so AutoCAD appears to remain locked up. The only way I have found to fix this is for the user to close all other programs, then use Alt+Tab.
I have tried to check the value of the system variable TASKBAR, but AutoLISP getvar returns nil, and VBA GetVariable produces an "Error getting system variable" error.
Does anyone know of a good solution for this? Any help will be appreciated.
