I believe this problem started with v2.23o. I keep losing the filename and path as soon as I click on a file and get a save error because I am saving to a filename with a null string. I uninstalled/reinstalled v2.23q and the problem went away, but so did a lot of my settings, so I resurrected a copy of Mp3tag.reg I saved just before I uninstalled and restored it. The problem is back and Mp3tag is not useable. I'll try to send you the REG file.
P.S. I repeated the uninstall/reinstall of v2.23q and this time edited the registry file I sent to Florian via email to restore only those things that I really needed, mostly lists and the sequence of my actions. The program does not lose the filename or path of selected files and is back to normal.
I don't think so, because when the problem was there, the first thing I did going in was to click on a file. Immediately the filename and path fields went blank. Trying to save the tag showed that those fields were blank in every way. I suspect this entry in the registry:
Could I have gotten messed up by restoring the latter into a version that expects the first entry? The problem however, started before I ever tried to restore the registry. Could it possibly be a problem related to skipping a release that handled the delimiter change?
