I am aware that other people have tried to resolve this issue but have thus far found a suitable answer.
The error is, on start up, eclipse gets hung up on \"Android SDK
I used the answer above - first installing cygwin to get the Unix style "find" installed (note that the DOSbox "cmd" version of "find" does not work - in the following line at the top of your Eclipse workspace that hangs:
find . -name .markers -print -exec rm -i {}
Note that the "-i" specifies "interactive" remove - and will confirm each ".markers" file that is to be removed. Then I followed this with a
./eclipse.exe -clean -refresh
in the eclipse folder. I will check again (after the next hang :-) to see if just the second line is all that is necessary. Anyway eclipse is happy again and so am I! Note that installing the full cygwin package takes a while (many hours) - but it is worth it - just start the install at the end of the day and let it run overnight...
