out of memory exception

I got the following out of memory exception while using the SyntaxEditor control. Wasn't doing anything special other than just typing. Not sure if you have an idea about the cause of this or not or even if is entirely related to SyntexEditor but since the exception only lists ActiProWinCore and .NET Framework, though I would let you know:

System.OutOfMemoryException: Out of memory.
