Hi There,
I had developed an addin for PowerPoint 2007 which is having a custom taskpane. The custom taskpane contains three toolstrips which contains buttons and on click of button, functionalities execute like Color Fill, left Align etc.
Everything works fine but whenever I select any object(autoshape etc.) and hover the mouse over the dropdown menu subitems within the toolstrip, move the mouse to other location and wait for few milliseconds so that the dropdown automatically collapse.
Then after the collapse of dropdown when i move the mouse back to slide and try to select any other object, then powerpoint got hang and shows very abrupt behavior like if you press enter key, two new presentations open automatically and if you press arrow key one presentation per key press opens.
But if you click the button on the toolstrip dropdown then everything works fine.
I am using MS-Office 2007 SP3.
The things I had tried till yet:
1. Created another addin which only contains the controls but no code, just to verify whether the code I had written is having some issue. But the problem still exists. I had not even handled the Button Click events within the new addin but still if i click on the button inside the dropdown, everything works fine and nothing hangs.
2. ServicePacks is also not an issue.
3. Tried to invalidate the toolstrip using code but failed.
Kindly look into the matter.
