Did you find the option to use spaces instead of Tabs ? Or you still have problem with this ?
It seems the default parameters in IDEal have changed because now the source doesn't get changed from spaces to tabs. It all works fine, and I have tweaked the parameters in order not to get into the same situations. So that to me is a resolved case.
The biggest problems I had with IDEal at the time I posted that was various unexplained crashes. So, that is why I wasn't yet ready to use it. So, I put it on the side and went back to the blitz IDE. Then I started using Protean, which wasn't as entertaining as the blitz IDE for some things, but had some stuff which I needed: ie handling big sources, and... That's it!
For an IDE to be real useful to me, it would need to contain a DIFF system (compare 2 versions of a source), and a way to trace execution and compile error logging. Those are things that exist for ages in IDEs from say, Borland Turbo C or Turbo Pascal.
You've got something good to advance with still. I'll try to keep using IDEal none the less. Hopefully I won't encounter a bug that will demolish my source files or crash miserably and corrupt anything.
