I recently updated to the 1.58 Object Dock Plus and had to go back to 1.5 for several reasons.
The two worst problems:
1. Some of the icons on a tabbed dock automatically change to an extremely small size - and reseting them doesn't work. Not all, just some - and apparently random.
2. Saving a theme configuration - and then trying to re-Load it always generates an error. I can create a new layout and then Load it with no problems. However, I have a highly configured tabbed dock that I absolutely don't want to lose - but it either won't save it correctly by corrupting it - or won't load correctly.
If I uninstall the 1.58 via Stardock central and reinstall 1.5 - then everything works fine.
I am running Vista Ultimate, Acer Ferrari 4000, 1Gb RAM, 2.0 AMD Turion 64 processor, 128 ATI x700 video.
