Hello,
I and some others in allyh ran into problem with macros for N52: fast quickbar switching does not work reliably, it skips ALT key somehow. Resulting in pressing F key instead of switch to quickbar. This little solution may help: record the macro with timings. Usually those ms of pressing the keys are not necessary, but in this case it helped me. Now I can fast switch again :)
All other things like perma-shift etc are working fine so far. Except one thing - I somewhat cannot make the wheel pressing to work.
