Ok, I think you are safe to install iSolitaire now! The quick update to version 0.81 fixes the bug that did not allow a new deal. After updating to 0.81 I was able to select a New Deal with no issues. The Options menu still only has the default theme but, other then that it seems to be working normally on both 1.1.1 and 1.1.3. If you are on 1.1.3…install away…if you are on any other version (1.1.2 and below) I would say there is no need to update, version 0.81 does not add any new features and actually takes away the ability to change the theme. iSolitaire is available through the Chris Miles Repository. Below are the screenshots.
Note: If you have already updated to iSolitaire 0.81 and you would you can get version iSolitaire 0.71 through the Ste Packaging source.
