Been playing about for a day or so now, and discovered that when I try to delete additional filter conditions, I get an error: "Access violation at address 0000000000000000 in module 'netscan.exe'. Execution of address 0000000000000000." However, I am able to close this message and carry on using the app, and the filter is removed.
Whilst on the subject of filters, but for Port Mapper, there is no ability to add additional filter conditions, is there a reason for this?
That is indeed a bug, which surfaced recently due to an improved memory manager. Thank you for reporting it. We have just fixed it in the latest builds - please update your installation.
Regarding the filter in Port Mapper: at the moment only one filter is supported, i.e. only one condition can be specified. I'll check if we can implement multiple conditions support like in Network Scanner.
