Thanks a lot for all the responses.I am sorry that I did not check the forums for last few days.
I was using Linksys Super G router which I changed to Netgear N recently. All my tablets are still having inbuilt G card and I have not made up my mind yet whether to change them to N.
My problem is better but not resolved since the change in router.Whenever I lose connection, I always press yes (never no), but most of the time I'll be bumped off and lose the data.
I still believe that there should be a simple "save" button (in stead of complicating forward button, which people can periodically press to save their data, which is available in most other programs.
The idea of using a wired desktop via something like logmein looks also attractive.
But to go to next level, we have to have a simple save button to keep on saving info as we go.
