(again) scantime - now arch module 1082

Hi,

About a week I saw suddenly an huge increase of the scantime after the update of Archive support module version 1080:
Scantime after Archive support module version: 1080

After the update to archive module 1081 (20090205) it was back to normal.

Today I got archive support module version 1082 (20090213) and it is giving me again a much longer scantime:
From the usual 27 minutes it was now 66 minutes.

What is happening ?

Again it seems to me that in particular the scanning of .bin files in installation files is taking longer.
And again I see this, for example:
D:\Outpost Pro\Version 6_5_2358_316_0607\OutpostProInstall.exe »INNO »setup.data - error - unknown compression method

And yes, I have deleted several too old install files.
