OK - since you DID ask. FYI - I actually Step thru the code - and when I do - everything works fine! That's why its an even stranger conundrum!!!
Also - as previously mentioned - I actually Was testing on a machine that has the problem. And, even on there - when stepping thru the code - the problem then does NOT occur...

This has the smell of a race condition. You might not be able to get at the actual cause. You may have to -- shudder -- kludge. If someone comes up with a non-kludge, use that in preference to this.
On a misbehaving system, try adding a sleep(10000) between each statement. Does the problem still occur?
If so, come up with something else to stick in a delay that gets rid of the problem. If it is response-related, try a keyboard-messagebox() sequence.
If not or after finding an alternative delay method, start removing the delays until you find where the problem triggers. Keep that one. You might shave the time down some, too. (I selected 10 seconds as overkill*.)
After getting it to the minimal number of delays, try removing them all. This might work. Why? Who knows?
