I just tried to use the Muegge filter and IJC gave the following error. Any ideas what's going on?

I just found out that the problem appears to be the filter selection pop-up window.

If you select 1 filter there is no problem, but if you choose another one the filter parameters are added to the filter-1 parameters and the text in the filter query box becomes red.

You need to select the filter parameters with the cursor, delete them, and then select another filter.

Is this a bug?

No, that's the way its supposed to work. This allows you to add multiple terms to the expression. But if you do this then you need to ensure that the terms have appropriate separators between them to make the text a valid expression. Typical separators would the the normal maths operatios (+, - *, /) and logical oprators (&&, ||) are obvious examples. The chem terms reference guide gives some good examples.

As you noticed, you are notified when an expression is invalid.
