IE-related Spybot problems

[Renegade334]

Hello, I'm new here to the forums and I've registered to enquire about a certain problem that has plagued me for a short while.

System: MS XP SP2, single user, AMD Athlon (XP) 3200, 2.20 GHz.
Browser: MS Internet Explorer 6.0.2900.xp_sp2_rtm.040803-2158

I've recently replaced my Spybot 1.4 by the new 1.5.1.15 and at first I was satisfied with what seemed an improved interface and search engine. However, I changed my opinion after my first try.

I happen to work with a lot of .html files friends send me for proof-reading and editing and I use IE by default (force of habit and for practical uses) to view those files (I use Frontpage for edits). However, after I first used the new 1.5.1.15 version, I've been having trouble opening those files with IE; 'IEXPLORE' does appear in the task manager but it takes it takes its sweet time opening or I get a message telling me IE didn't find the file. As if that wasn't bad enough, it seems it's messing with my browsing too, as website layouts are either incomplete, refuse to show up or lead me nowhere.

Since I have two 200-Gb HDs with 5 partitions in total, I thought copying and pasting the files from one partition to the other would fix an issue I first thought to be hardware-related. Didn't work. It's only when I realized that 1.5 might be related to this bug (after all, I only installed two new ad-hunting related programs and the other one seemed completely blameless on this) that I decided to uninstall the whole thing and go back to 1.4.

Ever since I reverted to the previous version, I haven't had any problems and I'm peachy with it. Is there something I must do with the 1.5 to circumvent this nuisance or has it been fixed with the new RC for 1.5.2 and I can have a new try at 1.5? Or should I just stick with 1.4?
