Bug report:

EmEditor 7.00 all RCs
Save settings in INI files
Tabs disabled
Open or edit file with EmEditor in 7-Zip

When you open the first file in 7-Zip, it’s OK. But on the second file, EmEditor said system can’t find the specified path.
If you save settings in the registry, or you enabled tabs, there are no problems at all.

Maybe you should make more RCs… :-?
