A family of Microsoft relational database management systems designed for ease of use.
This also just started happening to me. You go to filter on a field or sort using the menu ribbon or right-click options and Boom! It crashes and tries to save a backup copy of itself. Any recent changes you made to other queries or objects that you may have been working on, but not yet saved, are lost.
It seems to be a recent development in the last few days. This occurs working in the very same set of MS Access databases that I have been working in for a number of months with no problems at all, so I doubt it is a problem in the database. I run compact/repair fairly regularly, and the databases are all reasonable sizes ranging from 50 MB up to 1,500 MB
Some of the databases are 'front-end' databases have queries used linked data tables housed in a separate MS Access db on the same local drive, some connect to data tables in a separate access db on a network drive, and some are just when querying data tables within the locally-saved database.
I'm doing a lot of work exploring data, and this is happening to me every 10 to 30 minutes. I hope they figure this one out as it is hampering my productivity.
