The tool "Notepad.exe" that comes with Windows operating systems is what I use on a very frequent basis, and about 4 years ago I found that every time I performed a complete harddisk format and new installation (to clean and optimise, etc, yada, yada), Notepad would change in performance, on some installations I found that inserting or removing new lines, or replacing highlighted text in documents (those with huge amounts of text) would cause a slight delay (a.k.a. lag), while on some installations I found the lag to simply not exist at all with no trouble (and we're talking the same machine here, and same installation). I later found out that is was the additional language support that came with windows that was the cause of the lag, and that by not installing the additional languages (ones I didn't need) would allow Notepad to insert/remove/replace strings of text with no lag at all.
To jump ahead now 4 years on, I recently got a new computer because my old one was taking its toll on me, unfortunately it came with Windows 7, and I wasn't able to downgrade to XP like I wanted, but no matter, I can deal with that as I am not too fussy with these things (I can learn to live with a few bent rules), however, I found that Notepad had the same issue of lag that I explained above, now at first I assumed the lag was caused by the same issue as XP's, but with it being slightly hard to navigate around 7, I haven't been able to fully look into languages, it seems that a certain language install/remove section that was shown on a page explaining "how to install/remove languages" doesn't exist on my side, hence I'm assuming there is only one language support in use at the moment, and that is the one I'm using now.
This is where I look to you lot retro for your wisdom, if language support is not the cause of this lag (in this instances), then do you happen to know what the cause is? And if so, do you happen to know how to remove/resolve it?
I'm really not happy with having to wait a few seconds for a new line to insert, and I cannot accept the fact that inserting/removing/replacing text on large documents in Notepad on Windows XP would have no lag at all, while 7 can being the newer software and being on a much faster machine, that just seems like bullshit to me...
I would also like to point out that I have no intent on looking for another text editing tool (because I shouldn't have to really), so please don't recommend any.
