Worked with F5-refresh but not automatically.
enabled immediate switching in KM 1.54 and KM 1.6.
Interesting - which options were that? <curious>
Sorry, tried everything, with backups, but can't reproduce.
I thought it was allow hiding or something similar.
If disabling or enabling takes more time, not sure, but guess both actions usually 'feel' rather similar time-wise.
There is no Internet access while switching and
the slowest memory eating part in KM is its GRE.
If window creation in KM 1.6. changed, and they're
now built dependent, they receive the same messages.
My suspicion has always been that it's a gecko thing,
Then download both Geckos and compare.
I'm still busy with favicons and if any KM-Code
is involved it will show up while disabling functions for testing.
