I have this problem with this looong window...
this problem i have on WinXP & Win7 x64 and only on russian version 20.5 and 20.6, but on v20.4 dont have this issue, i also testing NIS v20 - same problem),
i dont want use version 21 (21 is good but my favourite is N360 v20) and especially dont want to use v22.5 (hate it).
On v20.6 english version all very good (dont have this problem).
Please fix this problem (ehy this windows so long?).
And please create installer for versions 21 with version 21.8 or 21.7 for installing on Win10, unfortunatly i cant install 21.6 on Win10 (dont work)
