Freeplane does not start

  • Check that the java runtime environment is installed. Sun JRE 1.6 or later is recommended.
  • Run freeplane.bat (under linux run freeplane.sh) from a shell and look at the output printed there.

If you can not understand the reasons for failure yourself, open a bug request and post there the output.

Html text and images can not be pasted from Web pages in nodes and notes on Linux

It is a java issue on linux. Use Firefox for Windows with Wine.

Links don't work in Flash export

This results from security policies for Flash. Flash works differently for local and internet swf files. External links can not be accessed from local flash files by default. The permission can be given using link http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager04.html . The links also work fine if you upload your flash to a web server and access it using http protocol. Everything is described on page http://www.adobe.com/devnet/flash/articles/fplayer8_security_03.html

Nodes are not displayed properly on linux if the map is zoomed

Install the latest sun java from http://www.java.com/de/download/. The open jdk behaves buggy and is also significantly slower.

I cannot find the spell check function

The spell checker has to be enabled, see the Spell checker how-to.

The editor freezes

Create an entry in Mantis and provide as much information as possible about the conditions under which the behavior occurs:

  • Does it happen always if you do ...?
  • Is there a dependency on the size of the loaded map(s)?
  • Post the output of "java -version" (it contains the build number)
  • Do you have something special in your environment?
  • Is Freeplane consuming computation power when it freezes or not?
  • Before the freeze, was there any activity in the logfile? At least if there is anything suspicious, please post the logfile.
  • Can you stop it with normal means (close window, send SIGTERM, ...)?
  • Try a downgrade to an older Freeplane version - does that help?

It would be of great help in any case if you would provide a listing ("stacktrace") of what Freeplane is currently doing when it freezes by using the jstack tool. Find out the process id (PID) of the Freeplane Java process instance via Taskmanager, top, ps or whatever tool. Let's assume that the PID is 2345. Please post the output of

 jstack -l 2345

(You have to replace "2345" with the real PID.) For comparison also post the jstack output of Freeplane before the freeze (if possible). As you can easily check by inspecting the output it's pure technical stuff, nothing of your private mindmap is contained in it. Unfortunately you have to have the JDK installed to use jstack (the JRE wouldn't suffice). Please tell us, if you cannot install the JDK for some reason. - We might be able to help.

For more on jstack see its Sun documentation.

SourceForge asks me to log in repeatedly

This happens if you log in to SourceForge using OpenID. First log out, then create or log in to a full SourceForge account with a username and password. SourceForge support for OpenID is very limited and has numerous known issues, including incompatibility with our Mantis Bug Tracker.
