    Hey TimR,

    i'm trying your software but it is crashing all the time. I'm using this Beta from this thread here. The Error is named: Access violation at 0x774b2591 (tried to read from 0xf4f1a04), program terminated.

    Once the software started but it crashes immediately. I'm looking forward to hear from you.


    Vista Business & Intel ABGN WiFi

      My WirelessMon 3.0 and Vista crashes too!!!!

      I have one of two symptoms.... Either it starts up and runs until you click on it or 15-30 seconds pass and it crashes. The other symptom is the Access Violation error....

      The Vista Problem Details (or App event log) show...

      This is a great application and it's causing me pain not to be able to use it!!!

      This all started sometime in the past week or 2....if its the same time frame as others, could it be an update of some kind???

        It seems that Vista SP1 has changed some of the underlying system functions that WirelessMon uses and is causing it to crash. We are still trying to figure out why SP1 is causing the crashes and the minute we do i'll put up a new debug build.

          There is a new build debug build available, if you are having problems with running WirelesMon on Vista please download and let us know if it has/hasn't fixed your issues.

            Also if you do get a crash, you will often see a window asking you to submit the error to Microsoft. PLEASE DO THIS.

            When you get the error (from the error Window, select the "Send Error Report" button). We can collect this detailed crash information from Microsoft and this will give us more information about the problem.

              Downloaded the new version of WMon but it didn't fix the violation error and i cannot click the send report to microsoft button because it didn't exist in this window. I think it's not a SP1 problem because i haven't got Vista SP1 (Vista OEM) . Hope you will find a way around this problem. It's a very nice program!

                After the initial crash window there should be a "Check for solutions" window displayed, if you click the check button it should send a report to Microsoft.

                    There is another new build available fixes a subtle bug in the access point detection update loop which caused a number of crashes in Vista. The software was crashing if a new access points appeared while we were already half way through getting the list if available access points. So wireless cards / PC's that were slow to report data were more impacted as there was more chance the list would change in the middle of an update. Hopefully this is fixed now.
