IDE BUG?

[+tomanycars]

has anyone else had any issues with copying and pasting code into the IDE and it carrying over erroneous invisible code that the IDE doesn't understand ?  , I copied some code over , and i noticed that it carried some random code at the beginning of the line  its only visible if you highlight it.

perhaps there are not enough characters ; { } or vice versa there are more of them than necessary

i'll keep an eye on it. , it does seem to be only when i copy over code and it carries some weird extra code.
