I have recently downlaoded the trial version of v1.02, and I am experiencing similar problems to that posted by 'Letum' on the 30th April under the post heading of 'Was working, kerblam!'
When moving to the secondary machine, multiplicity unloads on the primary. To get around it, I am currently using the Scroll lock switching option, but I occassionally accidentally move to left side of the screen on the primary where again, it unloads.
I thought this problem was fixed in May..either that or it is a different problem. I really love the program, but won't buy if there are prohibitive bugs...
Please let me know if you can help.
