It's a real pity, but I have no idea what is causing the crashes of the new tis component, nor how it can be fixed.
If anyone more adept with area making can give me the solution, I'd be very grateful.
Apart from that, I have a new version ready that fixes some small things, e.g. the OSX install fix. As for the crashing tis - all I could offer is disabling the optional component until someone provides a fix.
