If you create a variable and make the value big enough AND WITH NO SPACES, the whole program freezes for about 1 minute, and then resumes as normal. It doesn't affect the rest of the computer. Aptana's "debugging variable values hover box" already truncates really long variables eg "Hello World" might become "Hello W...." however it can't handle massive variables with no spaces in it. If the variable is only a thousand characters long, there is only a 2 or 3 second freeze, however if it is several thousand chars long, the timespan would be several minutes, by which time a dev has already given up and closed the program with a Task Manager.
The problem seems trivial, however it is an issue for someone trying to calculate large numbers eg Pi to 5000 decimal places. there obviously wouldn't be any spaces in that value, therefore Aptana would freeze.
Thank you for your time.
