I can't find the " - " sign under Arithmetic operators in Iqan4.
I can´t find it in the list either, but the simplest workaround is to hit "-" key, and then select it in the drop down menu.
This is already on the bug list from the IQAN designers
Please be patient till we get a message, it is solved
Fixed in 4.01 which is planned for release first half of February. Meanwhile please use Daniel's workaround.
