The first two problems you mentioned:
- Some actions in the pop-up window where deleted
- Close window ineffective in an image or button added on pop up window (before it was working)
>>We also found the popup window problem with TW 4.00.081127. When we add a button to a popup window, and add "open popup window" action to the button to open another popup window with background image,the background image of the second popup window does not show. So we fixed the bug and released another update in 4.00.081128. Sorry for the confusion this may caused. If you indeed used 4.00.081128 to publish your previous project and still have the above problem, please send your project to our support and we will have a test.
The third one,
"Loading process : it get stopped on 11% then goes directly to 49% and loading the image 100%"
>>The loading bar progress is affected a little when we tried to solve the loading speed problem, but the progress bar will not stop on certain percentage. Can you tell us the tour link?
We are doing our best to improve the viewer quality of TW4, and we hope to release an update before end of December. Meanwhile, you can use smaller sceneviewer window (within 800*600) and choose playing speed under 4, to offer better viewer experience.
