UpStage v2.1 User Manual


UpStage is a work in progress: it is being maintained and developed by volunteer programmers, which means that things happen but sometimes slowly, and sometimes things break as we go. We welcome input from anyone who has the time and skills to work with us on the development of UpStage - please visit the SourceForge site for more information, and join the developer's list.

If you encounter a problem that isn't listed here, or that you still can't find an answer to, please:

Browser Problems

We are constantly monitoring browser compatibility, so if you experience problems connected to your choice of browser, please contact us.

If you are having browser problems, we recommend the following:

  • ensure that you have at least version of the Flash player installed;
  • close your browser window, open a new window and log in again. If you still have problems after doing this, quit your browser application and restart it.

Stage Won’t Load

If the stage fails to load properly, and the splash screen remains over the stage with the message “Couldn’t load all images”, this could mean that there is a corrupted image assigned to the stage. 

The first thing to do is try reloading, as it could just have been a blip in the data flow; either use the “reload” button on the splash screen, or use the back button in your browser to return to where you can from and click on the link to the stage again.

If this doesn’t work, you may need to remove a rogue image from the stage. If you had just assigned a new graphic to the stage before you encountered this problem, then that is most likely to be that one that’s causing the problem. Try unassigning that image from the stage, and see if it will load.

If you don’t know which image it is, you may need to take everything off the stage and reassign them one by one or alternatively, delete the stage and make a new one.

Fonts look bad

If an .swf file has been saved as low quality (in the original file), it can force the whole stage to appear “low quality”. This can be changed by right-clicking (on a Mac, ctrl+click) on the stage, and selecting “Quality” from the menu that appears. If Low is selected, change it to High and you will see that the fonts now display properly.

However, this will only correct the problem on your machine; your audience may not know how to change the quality. A better solution is to work out which image is causing the problem, delete it and resave the original file as high quality. 

Linux Fonts

If you are using UpStage on Linux you may find that fonts are not appearing on stage. This problem is fixed by installing additional packages:
