Hi @jacekkopecky long time no see. Are you now vmp user?

Btw I can see how this happen(bad code I should fix), but cannot understand why this happen? Since I cannot reproduce it. Can you reproduce it always? Any additional condition to repro?

[jacekkopecky]

Hi @t9md, yes, I've been using vmp for a long time now (of course); I never regained time to work on vim-mode after the summer of 2015. When I have some time, I want to have a look at vmp, but you've been doing a great job! 8-)

But to the issue at hand: I'll see if I can reproduce it outside my environment.

[t9md]

OK.... Let me clear, at least one PC you can reproduce issue always by just o escape . three keystroke?

[jacekkopecky]

It's the Group Changes When Leaving Insert Mode setting, when false, the exception happens, when true, it doesn't.

[jacekkopecky]

Yes, always o<esc>. triggers it.

[t9md]

OK, thanks! will check!
