I assume you will have posted without all the text, so I just posted it with a paragraph and it submits correctly.
I then edited the skin and put everything down to the Version history in and hit submit and it still worked.
If I then try and paste the version history it get stuck in the submit loop.
Version 1.4:
* Added rectangular Volume skin - toggle playback device, mouse wheel scroll or click on bar to change volume.
* Added playback device toggling to Round Volume control.
* Added Round GPU Load Meters.
* Added GPU VRM Summary skin showing voltage and temperature skin for over-clockers.
* Added Round Swap Memory (Virtual Memory) meters.
* Added Hard Drive Read/Write Summary skin showing current & Max values and disk activity.
* Minor tweaks and fixes.
Version 1.3:
* Altered the widths of all rectangular skins to be identical, the 3 that were smaller made no sense to my eye! Essentially LuaCalendar, Media Player and Slideshow get bigger.
* Added drive usage bars to Hard Drive summary to better utilise the space.
* The usual fixes & tweaks I forget!
Version 1.2:
* Motherboard
* Dual GPUs
* Hard Drives
* Analogue clock
* Launcher
* Slide show
* Round Wifi & Battery meters (tested on a laptop - screen shot is from my main PC hence no Wifi signal)
* Skinned LuaCaledar
* Quote of the Day
Version 1.1:
* Replaced Speedfan plugin with HWInfo.
* Added a GPU skin.
* Fixed some minor display issues with a few meters (showed % where not required).
* Changed the Players method of jumping around tracks from invisible boxes to a mouse variable.
From this it would seem there is a limit on the number of character in a description which is causing the failure but without providing any kind of feedback.
Pumping the whole text into Word gives 768 words, 4,360 char with spaces and 3,638 without. So, what is the char limit for the main text box? this might confirm the source of the problem.
