Xolox 1.11 crashing after aborting file transfers

This has happen twice now, I tried to abort a file transfer and it just stays there saying aborting. No one was trying to download the file and the rest of my downloads keep working fine. When I close XoloX (still aborting) I get the following error

Exception EInvalidPointer in module
XOLOX.EXE at 000027FC
Invalid pointer operation

It locks up my computer and I have to hard reset

I also woke up this morning and my computer was froze with a blank black screen. XoloX was the only thing that had been running.

I run Win98 SE with an AMD Athlon processor and Norton Antivirus
