Version: 1.7.0 (using KDE 4.1.0) Installed from: Fedora RPMs If you turn on the "autosave every" option in export to graphics file, regardless of the time setting, kst saves as often as it can (or every second, it's hard to tell). kst should only save the files every X number of seconds as indicated.
Modified _savePeriod from bool to int, in kstgraphfiledialog_i.h This had been incorrect since it was originally added in revision 367308.
