Apparently Intuit made a bigger change in the underlying database than we had been told. They moved from Sybase 11 up to Sybase 16. Along the way, something was broken. HOPEFULLY this is the only break, but we don't know yet. Right now, the following error ONLY has been reported by those using QuickBooks Enterprise 16.0
If an SDK add-on program performs a "customer query" (which ALL of our programs do), QuickBooks will crash.
Word is that it is going to take Intuit awhile to get this fixed - probably with the release of R4P (which has historically been late November to mid-December).
