ginput does not work in 2015a on ubuntu 14.04

I have a strange problem: I wrote a script using 2011b some time ago on a mac OS X and it worked perfectly, but now I try to run it on my office workstation running ubuntu 14.04 and Matlab 2015a, the ginput function does not respond to my mouse click anymore. My code looks like this:

...

figure (1), a 3D isosurface plot

...

figure(2), involves ginput

and now the problem happens.

I've tried a different script where figure(1) is a simple sin function plot, then ginput in figure(2) seems to work fine. So what might be the problem? I hope it is nothing to do with my graphics card (nvidia quadro K2000D). Many thanks!

There is a known issue with "ginput" when creating multiple figures in R2015a. As a workaround, place a call to "drawnow" after each call to "figure".

Thanks. Didn't see your comment until now. Yes, I've installed 2012b in the same machine and it works fine. So it is the version problem.
