I pulled up Sales Orders on QU-B, selected a given date from the calendar and the appropriate filter grid appeared after a few seconds.  However, the default sort sequence is By Est. Ship Date.  I pulled the drop-down box down and changed it to By SO Number.  The records on the grid disappeared and it would not re-populate.  When I tried to go back in, I get a "FATAL ERR - File: caldrillbt.SRC Line: 456" message box that states "The field you are trying to use is unallocated. It may belong to a file that hasn't been opened yet, or was an array that was removed from memory - []TEMP0".
 
I click okay on the message box an another one appears except the title is for "File: ISTECH.LIB Line: 987".  I click okay and another one appears for "File: caldrillbt.SRC Line: 356".  I click okay and the 356 appears a 2nd time.
 
It keeps looping this until I give up and click Exit on the calendar screen.  When I do I get another message box for "File: ISTECH.LIB Line: 2201" which appears twice.  I now have to exit Evo as any further attempts to relaunch QU-B gives me an "Access violation at address blah-blah-blah" box.  In fact, clicking File/Exit on Evo will now do nothing and clicking the 'X' gives me another "Fatal Err" message box.  I have to right click on Evo's icon on the task bar and select Close.  I hear a few beeps from my speakers and after a few seconds, Evo finally closes.
 
I've obviously pissed Evo off really good at this point!  Any ideas?
 
Thanks!
