fold state is lost when switching between tabs with <alt right-arrow>

[GoogleCodeExporter]

What steps will reproduce the problem?
1. open two files at once soas to have two tabs open
2. contract some if statements in file1
3. use <alt right-arrow> to switch to the other tab

What is the expected output? What do you see instead?
i expect to see the folds as i left them.
the 'if's that were folded are now unfolded.

What version of the product are you using? On what operating system?
1.0.6
ubnunt linux

Please provide any additional information below.
for that matter, it would be nice that if I close a file and reopen it, it
would restore the folds as they were.

Thank you very much for this plugin as it helps a ton for looking at other
people's code.
