Question Problem with drop down box Arcgis 10 / Visual Studio 2008

[TartanRug]

Hi,

I have encountered problems with drop down list boxes (ddl) on forms since I have been using Arcgis 10.

When the arrow by the ddl is clicked with the left mouse button, the list appears then immediately disappears. The only way to access items on the list is to click the arrow and keeping the left mouse button held down move onto the list of items.

This doesn't seem to be normal behaviour for a ddl, is it a bug?

Any help appreciated.

Thanks,
Simon
