Richard:
I do feel for you. As most of you know I hate upgrade costs to software..any software. People like what they get to know. ( As John says, he much prefers Gearotic Motion to Gearotic Thoughts..( and yes, John I am striving to make you happy this season..

), and to me once you buy you should stay bought.. but I also understand why some companies have to charge for upgrades. But if the reason is greed..I get pissed off...
I wont do that, that much I do promise, I keep Gearotic Motion for those users that from time to time request it, and I try very hard to make sure GT will work on all machines. Anything I write is always in constant development, so you
poor folks do have to put up with my somewhat eclectic style of development and bugs that pop up from time
to time, so for my part I always promise to never charge you another cent no matter how large or complex
the program gets. Some lucky Mach3 users can testify that they paid only $25.00 for over a decade of upgrades. Some Gearotic users who payed $75.00 can also feel lucky.
True Story... I once used a program called "Involute Gear Generator", I was fully licensed and used it to make things in my shop. The DXF's in it were horrible though and I constantly had to edit them as they had crossed lines.
Eventually, the programs author offered an upgrade that fixed it. He wanted $125.00 to get the fix. I was pissed
at the thought of paying to fix a serious bug in a program I bought and payed for. Hence we are all here using
Gearotic. I truly wrote the program because the one I had pissed me off. I also wrote Mach1 because a program I wanted was way to expensive for what it was and that pissed me off too. So perhaps when you get pissed off at a company you should do as I did, write your own.
(Im just hoping I dont get too pissed off at Microsoft.. Id hate to invest a century or so in replacing it...)
