Try going through a few of these.... there aren't that many. Hopefully,
something will look familiar.

No.. Timers don't run on their own thread. Here's a snip I post once in a
while that describes how events work......
'===========
Timer events are not asynchronous. Events merly change the programs "current
instruction pointer" temporarily. It doesn't get changed back until the 'End
Sub' runs in the event handler.
Example based on a Timer event....
Private Sub ABC()
1 code here
2 code here
3 code here
'timer event fires after running line 3
'code in timer's event handler starts
4 code here
5 code here
6 code here
End Sub
Private Sub Timer1_Timer()
'This entire procedure runs before
'returning to line 4 above
'it will never return until the line below runs
End Sub
