I have an issue on two computers that after a while of using KNIME mouse double-clicking stops working or becomes very slow to respond. This is the case for all nodes where a double click is required to select a variable or column - eg Rule Engine, Column Rename etc. Mouse works, tried with different mouses. Not a button issue. Sometimes seems to be resolved by closing the Configuration window of the node and re-opening. Sometimes (for example in Rule Engine) highlighting the cursor again helps.

Have you tried to restart KNIME with the -clean option in knime.ini once?
