Break point not highlighted in source

Using: Build 944
OS: Windows XP Professional

Problem: When the application reaches a break-point, it stops but the source
file where the break is defined isn't raised with the break-point
highlighted. Also, because of this, though I can "step through the code" I
can't see the current line of execution.

When the break-point is reached, IDEA is de-compiling the class that has the
break point and displays this decompiled version (with no method bodies)
instead of highlighting the source file.

Note:

• This does not happen for all files with break points.

• Yes, the file with the break-point is part of the project's source path

• The application being tested is standalone and does not involve JPDA
