Running LW Pro 4.14.12.

First off - I have no problems with my Firewall etc. It worked from the getgo

I am experiencing LW freeze after a few days of operation. It seems to signal that it's about to freeze by a) slowing down which means that when I select a file for download it takes a minute or so to drop the file into the download folder.

When it does that is comes up with a message saying that (essentially) that LW has an internal error and that it needs to shut down or that you can continue what you are doing. Either way if I restart it loses my download library and all the files I have pains takingly research and readied for a download.

It does NOT crash Vista.

Some facts.
Using Dell XP dual core @2.66Ghz w 4gb ram
ATI Radeon x1300Pro.
1.5Tb HD's

The files I download are large (Audio books) typically >20mb and I will search and earmark sometimes over 500 (large) files. So my download library is pretty big

So I am wondering if I am stressing LW to the max and causing it to fail - anyone with idea's?

I am OK with rebooting but ticked off that I loose the library of files to be downloaded when this happens and have to start all over again
