trashed memory

Using QPro X3 on WinXP SP2
I've got strange behavior of qpro, building queries from long tables on the
same file to extract data to another table it happens that consecutive use
of that queries and alternating between several criteria makes the memory
to trash, and then extracts incorrect data or not data at all.
It happened too when making more different queries on another table in the
same file and then back to run first query I've got trash.
The only cure has been to quit QPro and restart again, but with same
problem, at times you only can do no more than 2 consecutive queries.
It's been observed in QPro X3 and QPro 11 on same platform.
QPro 1.0 for DOS was beautiful doing these queries before.
anybody has same problem?

Hmmm ... if the problem does indeed lie with the software program, you should 
encounter the same phenomenon with a different query run on different data in a

different notebook, using similar table and query dimensions (but NOT using the

same data or criteria).

Skeptical,
