Can't Properly Edit My Guide

[quote=Re4XN]Okay, this is getting really annoying: whenever I try to edit my guide, for instance, change a sentence, it takes a VERY long time to do so. I do realise my guide is really big, but I was able to edit it previously with no problems whatsoever. Now it can take up to 3-4 minutes for the text I wrote to appear. I managed to figure out a temporary solution, which is copying the entire guide (which also took around 5 minutes) to a .txt file and edit it there, then pasting it back. Is this happening just because my guide has a lot of text (in one chapter, if this is relevant) and my computer can't handle it (because it used to)?[/quote]
