Why sometimes the clipboard content got automatically transferred, sometimes not”?
Automatic clipboard transfer is very convenient, but it will increase the data transferred between the computers and create delays. As a trade-off, automatic clipboard transfer will work for text only. Also the size of the clipboard content to be transferred automatically will be limited (the limit is default to 5000 bytes. It can be changed between 0 to 50000 bytes by setting up a DWORD registry key: HKEY_LOCAL_MACHINE\Software\Potomacsoft\teledesktop\AutoClipboardTransferMaxBytes). If the size of the content exceeds the limit or image in clipboard needs to be transferred, you must use the toolbar buttons or menuitems. This feature is added since version 3.01.
