This update fixes a few small bugs.
You can either use the built-in updater, or go to the website and download it. There’s no need to uninstall the old version; that will be taken care of automatically.
Changes and fixes since v3.5.2:
- Fixed DirectDraw Surface (.dds) file format support for CPUs which do not have SSE2 (Pentium III, Athlon XP)
- Fixed an issue with the File->Save dialog related to file type plugins that were only written for opening (importing).
- Fixed some crashes which were supposed to be "out of memory" errors.
- Fixed a race condition with the New Image, Canvas Size, and Resize dialogs. If you typed extremely fast you could cause a crash by typing a negative number and immediately pressing OK or Enter.
- Fixed a File->Save dialog issue in Win7/Vista where it could ask you about overwriting the wrong file.

Just heard about another project called Pinta. Its an attemp to write a PDN clone for linux. Thanks for your inspiration and having been Open source. Check it out here:

About Pinta…for me…it’s more a Plagia than an inspiration.
I hope they write where this project comes from.
Paint.Net is Awesome.
Thanks

The developer of Pinta is very clear about “where the project comes from” on the site’s FAQ:
Quote:
Is Pinta a Port of Paint.NET?
Not really, it’s more of a clone. The interface is largely based off of Paint.NET, but most of the code is original. The only code directly used by Pinta is for the adjustments and effects, which is basically a straight copy from Paint.NET 3.0.
Regardless, we are very grateful that Paint.NET 3.0 was open sourced under the MIT license so we could use some of their awesome code. (If you need to get the Paint.NET 3.0 source code, you can get it from the paint-mono website.)
The author works for Novell, one of Linux major proponents so you can expect him to know about licensing agreements.
Oh and while I’m here, thank you so much Paint.NET team! Keep up the great work!
Not that these comments are the place to discuss this, but I definitely want to respect PDN with regards to Pinta.
There’s 4 links to getpaint.net on the Pinta website (which only has 4 pages), as well as the FAQ question mentioned above.
All code from PDN retains their original headers, as well as shipping the original license.txt. (Renamed license-pdn.txt)
Once Pinta has a real Help->About box, I’ll mention it there as well.
Thank you again for a wonderful, wonderful .Net app.
And if there is any thing else I can do to respect your work, please let know!
As always, thanks for the update. It’s immensely appriciated.
