I have now had two different incidents using two different sets of machines that is leading me to suspect there might be a bug in some recent update to Office XP or Windows XP.
Case 1: A database (front end) I work on at home on my Win98SE/Office 2000 machine and take to a client who is using XP in a networked environment with front end on the client computers and backend on the server. More than once I have taken a complete copy of various upgrades, sometimes on a CD sometimes via zipped file and emailed. When I install the new front end, it crashes on open. I solved this one the first few times by creating a new database and importing everything. This is a bit of a pain because I have to reset the DAO reference and rebuild a little custom toolbar. Lately, I just take the fixed/new elements and import them.
Case 2: This is the one that leads me to suspect it isn't something between my system at home and the first client's. I have another database I work on on my work computer (also Win98SE and Office 2000) where I have been emailing fixes and upgrades of the front end since February. For the first time ever, this client reported exactly the same problem and sent me a screen shot with exactly the error message.
All of this started about a month ago. Two totally different sets of systems with exactly the same problem cropping up. It's not unworkable but awfully inconvenient. Anyone seen this, know what is going on, know of a fix?
