The first time I tried to save my Design Table to a file I received an error saying the file already existed (It didn't) and asked if I wanted to replace it. I clicked on "Yes" and I received another error that said "Cannot save", but it actually did save the design table with "_new" tacked onto the end of the file name. (I've attached these two errors.)
The Design Table seem to work, but when I finish editing the design table a popup different than the ones above tells me the file exists and asks if I want to save it. Again, I get an error telling me the file can't be saved, but it does actually get saved.
When I rebuild and "save all" files in an assembly, SW pops open an Excel window and I go through a similar, but slightly different set of pop-ups, warnings, and error messages (most of the time), but again, things appear to get saved properly and otherwise the Design Table seems to work OK.
Am I doing something wrong? Or is this just the way it works?
