One of the employees who uses my app just replaced her old laserjet printer with an HP2100, which supports a native mode PCL driver and a backward compatible "5e" PCL driver.

Now,with either driver, my app, which is otherwise unchanged, breaks as follows:

(1)Run a report - report prints correctly
(2)Bring up order entry form - when DE of form attempts Openfiles() system locks up with the famous hourglass appearing and is totally unresponsive even to 3 finger salute and must be restarted with the reset button.

Tried both drivers with same results. Problem does not happen if print on another printer in net. Problem only occurs for this user.

Another clue is that when the system restarts, the printer coughs up a page with a few hearts printed at the top...kinda like an orphaned printer spool file is being purged. (This only happens when restart occurs after the main problem has occured)

Other apps, like Word, print just fine on her new printer.

I'm pursuing the hypothesis that something about the new printer driver is combining with VFP to overrun her 32 MB of memory in such a way that crashes rather than an orderly shut down or a 'you need more memory' diagnostic.

Any body else have a similar experience for which you discovered a cure?
