Stored position problem coming out of standby vu solo blackhole 1.7.9

hi,
i have just bought a vu solo original and i flashed it with blackhole 1.7.9, i have it set on diseq 1.2 because my dish is slightly out and i have stored the positions 01,02, ect for each sat but for some reason every time i put the box on to standby and turn it back on the dish seems to have moved slightly but if i press any of the limit buttons it seems to go to the right position again, it is like it is not storing the commands, is it possibly an image problem as i have just downloaded the vix 3 image to be ready to put on, it is doing my head in,any ideas?:waaaht:
thanks tony.
