About Zone Alarm with WinXP, there appear to be several teething problems. A message yesterday on a security newsgroup states that
"A few weeks ago as I restarted my PC, I was treated to a BSOD within one of ZAP's modules (I believe the module name started with "VSDATA"; could be wrong) and upon restart, I was treated to a second BSOD indicating that my registry was corrupted. I reinstalled XP without ZAP. The latest Windows Update contained a compatibility fix for ZAP. Has this fixed anything for anybody, or is ZAP just another roll of the dice on the XP craps table?"
ZAP = Zone Alarm Pro, BSOD = blue screen of death. No answers as yet. In particular, the ZAP support page does not seem to address any XP "issues" as of now.
