There have been a few reports of Note Taker HD freezing when it starts with a particular screen configuration as it tries to re-open a document for editing. The editing areas are blank, and only a few buttons are shown, with the eraser image over part of a "Cancel" button next to a "Paste" button. Quitting the app does not fix this.
This can be caused when you switch away from the app while it is in the middle of loading and hasn't completed the load and then later switch back or restart it. Stopping in the middle of loading may be more likely in iOS 7 when you see a screen capture of previous execution displayed during reloading after a task switch from an app that used lots of runtime memory (something iOS 7 does when it switches tasks) and on older, slower iPads. The app's saved "last page of doc viewed" value gets saved incorrectly. Subsequent reloads will try to reload that page and freeze.
To restore Note Taker HD to normal operation, use the "Open In Trick
" in the following way:
Get Note Taker HD to start on the List of Pages by using Mail or some other app to "Open In..." a PDF file
in Note Taker HD. (For example, use "Open In" from the PDF file Mark's Teaching Materials
on the Support web site.) When Note Taker HD starts and offers to import the file, press Cancel
to return to the List of Pages without importing.
Now that you see the List of Pages, tap once on the entry for the doc that was freezing. DO NOT use the "Open" button to reopen that doc -- that will try to use the invalid page. Instead, double-tap on the preview (opening to that page) or on the thumbnail (opening on the first page of the doc). The doc should open correctly. Use the Done button to return to the list of pages and all should be back to normal.
Contact us at the support email address if this doesn't work.
To avoid this problem
in the future until it is fixed in a later release, make sure that you wait at least a few seconds, or at least until the app seems responsive, before switching away from Note Taker HD when it starts displaying a doc. (Turning the iPad off or closing the cover is treated as "switching away" just like pressing the Home button.)
As always, do NOT uninstall the app when you have problems like this. That will erase all of your data. There is usually a way to recover your data and operation without that drastic step. Always contact Support for help in repeated crashing cases.
