It is not to blame Onedrive in this case, it it the inability of JuiceboxBuilder Pro to make use of the Windows temp folder. This is the correct location folder for temporary files.
I am using JuiceBuilder Pro since it came on the market and it was always running fine in combination with file synching programs.
We never get a new version or update after 2017 and technology has evolved in the last 9 years.
Webkit is replaced by WebView, IE 8 is obsolete and JuiceBox Pro is using Jquery 2.x and the latest Jquery is version 4 at the moment. Juicebox Builder is making use or supporting all this old technology
JuiceboxBuilder 1.5.1 is making use of old obsolete technology and this is causing problems with opening old galleries, the data is copied to the .tempGallery but JuiceboxBuilder is not opening it. Before creating a new Gallery we need to delete the .tempGallery manual because JuiceBoxBuilder Pro is using an obsolete API for it. The new technology can't be blamed for the issues and bugs with JuiceBox Builder Pro
What we need is a new up-to-date JuiceBoxBuilder Pro, visitors of the website can still buy a license of an old product, I don't understand this.
With my knowledge of Webbuilding and programming I am able to use JuiceBuilderPro but is this the same for other users of JuiceBox Pro
