<b>Photoshop 4.0.1 is out, although you may have trouble installing it

As now also reported on several other web sites, the new Photoshop 4.0.1 update is out, but several readers (including William Harris) confirm that it is quite finicky about whether or not it will update your existing file. Most often the problem is that it will not work if the name of the Photoshop 4.0 folder has been modified in any way (although some readers report problems even with an correctly named folder).

In another matter, Sung Chang writes that, after installing the 4.0.1 update: "Whenever I run a filter from the 'artistic' filters section, I receive an 'out of memory' error. I have 80MB of RAM with 50MB dedicated to Photoshop. This out of memory error only occurs with the built-in artistic filters. I have not had any problems with any third party filters."

Update: Raul Gutierrez notes: "Some of the problems people are having using the Photoshop 4.01 updater has to do with the fact that the updater checks for certain pirated numbers (the common ones available at Warez sites) and refuses to update those illegal copies."

Update: Ernst Mulder writes that both the enclosing folder and the application itself needed to have its original name. Even worse, "when the enclosing folder has any name other than 'Photoshop 4.0(TM),' but the Photoshop app is called 'Photoshop 4.0(TM),' the Installer will tell you 'An item called Photoshop 4.0(TM) already exists' and suggests to replace it. If you do, not only will the installation fail, you will also lose your 4.0 version of the Photoshop."

Update: Some good news. According to Mark Hattam, the Photoshop 4.0.1 Update also includes a revised Compuserve GIF that fixes problems with saving files in that format, as mentioned here previously.
