Problem with TLB

Hello. I have just downloaded the new version of Tlb. The program ist just wonderfull, but i have noticed one problem. Why making any change in Tlb settings area is taking so long ? If I wont f.i. change some option (even one), f.e. "show menu caption", tlb is working for even 1 or 2 minutes. During this time my whole Windows Toolbar is blocked. I can`t do just nothing. I see that most people are very happy with this cool program. But I am starting to be a little confused. I need to know what is wrong before I decide to buy and register your software. I am using Widows XP Pro and my `puter is after fresh reinstalation.
Thanks

1-2 minutes ??? This is too long What is your processor speed and memory size? Also can you check the Apply button before changing anything. It must be disabled. Do you use antivirus software that monitor files every time?

TLB can reload icons but not after changing "show menu caption" option. Somebody have same problems?

Just another question: how many network drives do you have? I notice HUGE delays when I have network drives that are unavailable. The entire process explorer.exe (including TLB) becomes irresponsive during this delay...

My computer:

Proc: Athlone 2600XP
Ram: 512 MB 333
Graphic: Gainward GeForce 5600 Ultra2 128MB
Main: MSI-KT4V Series
etc., etc.
I am using one hard drive (3 partitions) and backgrounded AntiVirus Soft AVK.

Dunno where the problem is
