Tree Explorer may not map mouse clicks correctly when DPI scaling is used

Microsoft Windows has a setting to "Change the size of text or other items on your screen" which when not set to the default value (100%) breaks the mapping of mouse clicks in the Tree Explorer window. The workaround is to set this option to the default value.

PDF images are sometimes cropped

Some users have experienced a problem where saving tree images to a pdf file results in a cropped image. This is a mysterious bug that we have never been able to reproduce. There are a couple workarounds:

  1. Save the image as a png or emf file.
  2. Copy the image to the system clipboard and paste the image into GIMP, Photoshop, or other image editing application. Then save the file in the desired format.

Note:
GIMP might complain that there is no data on the clipboard. If so, first paste the image into a Word file, copy it from the Word file and then paste into GIMP.

Starting in MEGA 6, older tree session files cannot be opened and alignment session files lose some information

A much needed design change in MEGA's session file system has made it necessary in MEGA 6 to disallow opening of tree session files that were generated using previous version of MEGA. A workaround is to open an older session file using the version that was used to generate it (older versions can be downloaded here), export the tree to a .nwk file, then open the .nwk file in MEGA 6. A new session can then be saved.

Additionally, when opening alignment session files that were created with previous versions of MEGA, some information is lost. The sequence data will be retrieved but the settings used for alignment as well as the form state (font, colors, etc...) will be lost.

MEGA for Mac Stability

Most Mac users have reported positive experiences when using MEGA (using the Wineskin wrapper and installer that we provide). However, we also have recieved feedback from some Mac users that have experienced stability issues.

If you are one of the Mac users who experiences problems with the wrapper that we provide, there are alternative options for running MEGA on a Mac system. For instance, MEGA can be run using virtualization or emulation software. Many options for doing so are available including Parallels (commercial), Crossover (commercial), VMWareFusion (commercial) or VirtualBox (free)
