TinyIDE is a 7.0 kBytes editor that offers a little bit more than Notepad, at least to the assembler programmer

Tested OK under Win7-32 and under WinXP with Office11, but the usual disclaimers apply, of course.
To use it, unzip the attachment to a folder on your Masm32 drive, e.g. to \masm32\TinyIDE, and launch TinyIDE.exe. Hit F6 to assemble & run the demo, or F1 to get some help.
Once you got it running, have fun with the sources in \Masm32\examples. Open, for example, \Masm32\examples\unicode_generic\multi_lingual\multi_lingual.asm and hit F6.
If you find typos in the box, open \masm32\examples\unicode_generic\multi_lingual\rsrc.rc and correct them - TinyIDE has no problems with Chinese or Thai...
The source is included: TinyIDE.asc opens best in TinyIDE's "big brother",
