I've got an odd issue that I'm uncertain how to resolve.
I'm running VSTO 2005SE with Office 2K3.
I've added buttons to the toolbars that open windows.
The odd thing is that when I click the button, it opens as many windows as there are powerpoint instances. I have no idea why a click in one instance causes the event to be run in all.
I've tried setting it so that it checks to see if the window already exists but because they're being opened by separate instances, this does not work.
Any recommendations would be appreciated.
Thanks
Denis
