[archive] "Disabled" Menu

[Migrated content. Thread originally posted on 06 February 2008]

Hi, All
I have a program that displays Excel spreadsheet names in a grid.
When I right-click the name I do a "C$System" call that opens the spreadsheet in Excel. When I close Excel and return to the program, the menu has been "disabled". I can click on all the options, but nothing happens.
Clicking on another control outside the grid will reactivate the menu. Does anyone have an Idea about what might be causing this?
