NSIS 2.30, MUI2: nsDialogs.dll remains after install

Just started to use MUI2 with nsDialogs feature.

After my installer finished, I find subfolder like nsgC3.tmp with nsDialogs.dll in %TEMP% folder.
Why doesn't installer delete this file after finishing its work?

That would be a bug in MUI2

you can use:

Function .OnGuiEnd
nsDialogs::SetRTL 0
FunctionEnd 

as a workaround for now

Just tested: this workaround really works!
Thank you a lot.

May you help me in my recent post concerning "SetRebootFlag true problem"?

Thanks, fixed.
