If your charts are posting blank or with a small red x top left corner try
1. Run Lavasoft Adware (or any other spam removal program you have)
2. Go to your browser
A. Click on Tools/Internet Options - Delete temp files
B. Click on Settings -- Setting for disk space should be around 100 instead of windows default of 2000 [note: Scylnx uses 10]
3. Defrag your HD
4. Cold boot - this means a power down reboot.
You should now be able to post charts again.
