"Another instance of GIMP Portable is currently closing. Please wait for it to finish before launching again."

I had just booted up, so nothing was ever running today.

Can you guys please correct this? GIMP is not "Photoshop" and should not be labeled as such. It is single-window mode not "Photoshop Layout".
It's like saying PA.Com is a U2 Drive software(Or whatever that software that comes on certain drives is;), which it is not....
I am sure that more than just one GIMP enthusiast is a little perturbed at this.

I'm unable to get GIMP to recognize any image file format other than its own .XCF format. Any way I try to open an image file (file open dialog, drag and drop, set GIMP to be default editor, etc.), GIMP simply responds with an "Unknown file type" error. Image files other than .XCF don't appear in the file open dialog unless the "All Files" option is selected, and even then GIMP can't generate thumbnail previews of them.

I'm sorry to break the silence.
John, I know you're tired of this - but the problem is that
App\gimp\lib\gimp\2.0\plug-ins\help-browser.exe hasn't
been replaced in 2.8.0 Rev 4 with the working one from
GIMP_Portable_Help_Fix_2.8.0.paf.exe

Just be aware that help-browser.exe must reside in the
App\gimp\lib\gimp\2.0\plug-ins folder.
In the above-mentioned fix it was mistakenly placed in
App\gimp\bin folder alongside with libgtkhtml-2-0.dll

Gimp new launched version 2.8 crashes on start up and will not load. The issues seems to be related to zlib1.dll I have loaded sample error messages here: http://greentouchpestcontrol.com/gimp-start-error.jpg

I welcome any help.

In the user settings,
the tool-presets folder is defined.
But it is never made in the user folder (data\.gimp\).
This makes the saving of tool presets unreliable.
The creation of ..\data\.gimp\tool-presets
fixes the problem, and makes saving the tool presets reliable and useful.

GIMP 2.8 requires saving to .xcf or exporting to other image formats.

A cloud scanner alert "A malicious item has been detected!" has started popping up after my last application update and pointing at a gimpportable sub-file.

Name: TrojWare.Win32.FraudPack...
Location: G:\PortableApps\GIMPPortable\App\gimp\lib\gimp\2.0\python\_gimpenums.pyd.debug

What is the best way of getting rid of the pop-up alert? I ran a scan with SuperAntiSpyware and the drive was clean so I don't believe there is a real problem. I tried hitting the ignore button in the alert window and was given the following(Ignore) choices:

"Once"
"Add to Trusted Files"

John, if you're not against, I will open a new topic for this little issue - I shouldn't have posted this in my "[Fixed] GIMP Portable 2.8.0 Rev 3 - Local Help error" topic

For some odd reason, *.tmp folders (names like nsr2D9B.tmp) are left in system %TEMP% directory.
It's not related to browsing help (as John has supposed in https://portableapps.com/node/32124#comment-194220 )
I do not open help and this still happens.
The folder is created when GIMPPortable.exe starts and contains:

launcher.ini
registry.dll
runtimedata.ini
System.dll

Is Python supported in GIMP Portable 2.8 without it having installed in Windows?
