Hi Jaime...

First off, don't go down the road of toggling your recordsource.....

Instead of making your main form main, why not use a PRG as your main. Something like:

*/ Set up stuff, menu, etc...
*/ Display the first form
*/ Read Events - or you can make the first form modal...

Then, when you close the first form - your EXE can bail

It is a bit hard to go further with much else.... Let me know how things go...
