Well, I tested beta2 and so far, most of the problems I noticed as relevant in beta 1 are still there. I'll try to explicit them one by one, and what cases they occur. 1- PG Usermode aspect ( procguard.exe ) crashes and closes, if an "unwanted" program is loaded 2-3 times, and execution protection is on. 2- BSOD (bad pool header) on several global Hooking programs. For instance, I have Visual Studio 2003. All the visual studio -related *.exe are on the list with full privilleges, and PG is in learning mode (this doesn't matter to the case, since I tested with or without, with same results). The system immediatly gives a BSOD as soon as I load a project file, even with "learning" and execution protection. I tryed uninstalling (deleting pguard.dat and hash too), and reinstalling... same results. The only way I can load a project file is by disabling the protection. I tryed with an empty list (nothing being protected), no special options like physical memory, etc... and protection enabled (protecting nothing) and still got a BSOD. Odd isn't it ? Same thing happens with Norton antivirus, Nero Burning rom. 3- It doesn't save the protection options. I tryed reinstalling Pguard (complete) , doing several restarts, but it never saves my protection options, like "physical memory protection", "block global hooks"... It DOES save when i disable protection, but thats the only thing that saves, whether or not the protection is ON. 4- Long periods of inactivity... let's say... 4 hours, pg crashes/closes. I have Windows XP SP2 with DEP only for "common system" (the default option). This might be the causer of this or not.. I don't know. 5- Block new and changed works for "block new", but some changed programs arr skipped on the " 'check' if changed " part. 6 -Some hardware changes makes Pguard crash. I connected an USB device, and Pg closed. After installing the device, all went well. I plugged in another, with same results. 7 - The "register" button never leaves the main screen. Shouldn't it leave after we enter the valid key ? Sorry but those were the troubles I got with Pguard3. There are several threads about one or other problem I referred, but they tend to be very specific, and I tryed to gather the problems I caught. Keep up.
