The MerckManual works fine, except it does NOT take advantage of the SD-1. It all stays in the 64MB of the GVM internal memory...and also very fragile, it crashed about once a month.
It is annoying, especially when you spent 2 -3 hrs to install ALL your favorite progs. I tried the trick to copy the gvm backup copy back to .gvm, it does NOT do the trick, or it does the trick but refuse to hotsync...oh well, I love the gvm, but it is so fragile . It seems the more 64 MB you use, the more it crash. Is that your experience? If so, install progs on SD-1 may fix it, maybe.
