Bracket autocompletion very slow in win8

Hi.
I've just switched from XP to Win8.1 Installed new PSPad. Checked "complete chars [({" (not the "smart completion").
And it started to do it very. VERY slow. It takes about 2-5 seconds to complete a single bracket.
The bigger the file, the slower is autocompletion. I've got worst results on 20kb file with program code.
The slowness is not persistent: first time it happens, then next char of the same type (eg [3s][0s]) is completed simultaneously. But after some time it becomes slow again.
Under winXP there's no such error.

Do you use the current PSpad version? At least 4.5.8, but I suggest you to update to current developer build 4.5.9

I'm using 4.5.8 (2500)
