Two Clicks Needed for ActiveX Controls

[FlyFishn4Bass]

I have several ActiveX controls on my worksheet (not a userform). For a while everything seemed to work just fine, however, recently (in the past few months) I've needed to push the controls twice (not a dbl-click, but 2 separate clicks) to get the control to function. In another thread there was a suggestion to use the "GotFocus" events, however, I'm having trouble with OptionButtons, which don't have such an event. I'm experiencing this on multiple worksheets, so I don't think it's anything in my code (unless I'm repeating a mistake in all my spreadsheets, but I don't think so). I also know it isn't system response (timing) issue. Sometimes I will wait 3 or 4 seconds before pushing the 2nd click, sometimes 3 or 4 minutes. The first click just seems to evaporate ... but the 2nd click always gets through.

Any thoughts on what might be going on?

I know I can backup and use Form Controls instead of ActiveX, but that dramatically changes appears and implementation.

Thanks in advance for any advice or hints.
