I tried 1.10 and it seems to work. The screen freezes as mentioned but i got my hits =)
Perhaps you could build in a Function to save the "Other MACs" or to open a List of "Other MACs"?
And it would be nice if the settings could be saved so that you don't have to change it everytime again.
I'm thinking on adding the ability for it to save settings to an XML file, or even some kind of config file. Then, custom MACs can also be saved there.
Edit: I'm starting on getting settings working right now. It took a while, but I'm implementing (slowly) the various settings, their loading, as well as their saving.
Edit 2: MAC Cooldown Value also saves properly now as well. I won't add custom MACs yet, but that's planned for the future.
Edit 3: Can someone confirm that CPU usage has gone down? I'd really like to know. picano
Edit 4: Added a ton of more MACs to the program, so Sequential and Random Non-Prime-Only modes can now cycle through a grand total of 160 MACs.
