I have several Windows 7-64Bit (Computers that have 4GB of ram, 3.5GHz).  After a couple of hours using Classic DBA, the program becomes so slow opening a screen (such as IN-B) that the time is upwards of 1 t0 3 minutes. Restarting DBA has no effect.  This is killing our data input efficiency. Rebooting the computer clears the problem, and IN-B loads in a few seconds.  This was not a problem until we abandoned the XP computers.  I would appreciate any suggestion as to how to troubleshoot this problem.  The only change was to upgrade from XP to W7.  All other parameters are the same.   Could it be a Pervasive (PSQL 9.5, V9.5.50.077.002) problem, and if so why would it have worked fine with the XP computers?  I have asked Tech Support this question, and have not received any answer or suggestion as how to cure this problem.  If you have this same problem, how did you correct it?
Thanks for any help with this!
