Summary: I'm trying to read the header file MVIRCNumerics.h from the open source Cocoa IRC client Colloquy http://colloquy.info. However, Xcode doesn't display the source correctly: it put in a strange blue hourglass image in the middle of the file, and some text is missing. Steps to Reproduce: 1. Open attached header file MVIRCNumerics.h in Xcode. 2. Scroll down to line 187. Expected Results: I expect to see line 188 and following immediately after line 187. Actual Results: There's a blue hourglass image in the header file after line 187. The text "#define RPL_LIST 322 // <channel> <#" on line 188 is missing. See attached screenshot hourglass.png. Regression: I can reproduce this problem on two different machines, an Intel Core Duo iMac and an Intel Core 2 Duo MacBook Pro. Another developer can also reproduce the problem on her machine. Notes: The problem does not occur if you open the header file in BBEdit or TextEdit. I also looked at the file in a hex editor, and there is nothing strange or different, no special characters in the area around line 187. 03-Nov-2008 06:43 AM Jeff Johnson: You can also fine the header file at http://colloquy.info/project/browser/trunk/Chat%20Core/MVIRCNumerics.h?format=raw. 03-Nov-2008 12:41 PM Jeff Johnson: The issue seems to be that Xcode thinks it's one big argument. You have the argument placeholder text "<#" on line 188 and "#>" on line 430.
