Both checkbox and radiobutton lose their appearance during Click event.

To reproduce just add checkbox to a form, set appearance to anything other than 0 and add this code:

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Private Sub CheckBox1_Click()
'simulate a long running routine
Sleep 1000
End Sub

When object is clicked it's appearance reverts to standard for the duration of the click event.

Can this be fixed for next version?

If your process is suspended like sleep you can't process any event's or windows-messages.

This is by windows-design.

I think, this can't be solved by CJ.

If i have long running functions i show a modal-form with a progress-bar and do some DoEvents.

Thanks Baldur. You gave me an idea.

The procedure is not that long running, just maybe half a second, but drawing problem very visible.

I thought maybe CJ could ensure control is redrawn before raising the click event.

However, adding DoEvents at start of click event procedure fixes the problem.
