ZAP 9.1.008 . Same version for true vector.
Win XP Pro SP3
My tvdebug.log file became monsterous in size , reaching 10 G and growing. zlclient.exe took a lot of cpu resources - two digits, sometimes more than 50%.
Had a chat with tech support and these two problems were solved.
Here's what to do:
1. Press Cntrl and Shift and Rt- click on the ZA icon in sys tray.
2. Choose set debug level.
3. Click on Off radio at debug categories.
4. Turn off ZAP.
Delete tvdebug.log. It resides at C:\Your Win folder\Internet logs
5. Restart your PC
I got a new tvdebug.log file with 1k size. zlclient.exe CPU usage dropped from two digits to zero.
