license.rev corruption?

[Ray Bennett]

I had my first Revolution "crash" this weekend.  The crash resulted, I 
believe, in my license key being corrupted, and I think that's probably 
it.   Anyway, the detail below is a little long winded, but insight and 
feedback would be greatly appreciated.

Scenario:
Was using the development environment running an application I'd built. 
   When the application is executing there were 5 stacks open.   All 
were "main" stacks.   The primary stack is used to input data which is 
used to retrieve matching data from one of other open stacks, and then 
update that stack based on new information that was input.

Each of the stacks may, based on the data it was fed, generate printed 
output.   For all of the stacks but one, when printing a card, the card 
is always printed into a rect, usually the rect of a hidden field on 
the first card of the stack.  The remaining stack (STACK D, lets say)  
uses cards which are always half-page in size, and therefore it prints 
the cards as a "job".

The target printer was an HP 4100 NT.  Printing via Appletalk.  Primary 
machine was PowerBook G3 Pizmo running OS 10.2.3.    The "Odd Things" 
happened using Classic Rev 1.1.1 AND Rev 1.1.1 for OS X.    Odd Thing 
#1 happened when running on OS 9.2.2 on a PowerBook G3 Lombard.

After running for several hours (in the Classic environment), Rev hung 
during a "Print Card" command - actually one that was generated from 
the keyboard.   I waited several minutes to let things clear 
themselves, and they didn't.  I used the force quit function, but then 
wasn't able to restart revolution at all.   That's when I switched to 
running Rev for OS X.  This ran fine for a couple more hours, then the 
same thing happened, and I couldn't get Rev to run at all.

Restarted the box.  No effect.  Eventually had to fileshare the stacks 
to another machine to get up and running.    When I got home last 
night, I downloaded Rev Classic again, and it ran fine.  I need my pro 
license installed to run my app so tried copying my license key over 
from the old area and restarting Rev.   It wouldn't start.  So, I 
simply put the new license key into the old Rev area, and presto, we're 
running again.

So, the $50 question, is the license key actively used while running in 
the development environment such that it can be corrupted during a 
"crash"?   If so, does this have any implication on standalone apps?

Just a little spooked.
Thanks.
