[Not related to Rubberduck after all] Saving XLA file with XLS is reverted when closing the files about rubberduck

[retailcoder]

I'm struggling to figure out exactly how Rubberduck is being involved here (other than being loaded), it looks more like it could be a glitch with the legacy .xla file format and/or Excel itself. Have you considered using the openxml .xlsm and .xlam file formats instead? Any bugfix or patch issued by Microsoft would presumably leave the legacy file formats alone.

Hello,

Thank you for your feedback. I thought it was because of Rubberduck because I didn't get the problem on a colleague's computer . He has the same Windows version, administrated by enterprise, same version of Excel, but no Rubberduck, major difference that I found.

I've just tested it again on my colleague's computer, after installing Rubberduck, and he still doesn't reproduce the problem. So it is not related to Rubberduck after all.

Sorry for pointing this issue, I'll keep looking what might cause this on my computer.

I'll try to migrate these files to the newer format, I think it's a good idea.

This issue can be closed.
