I've just updated my MMEX to 126.96.36.199 (Rev. 6147) and I can see that some of categories are not displayed at all in the account view (although when I display the transaction, there is category assigned).
Please, check the attachment: transaction 160,64 PLN is blank in the view, but when open you can see the category. The same applies to another transaction two rows below.
And I need to add that in 188.8.131.52 (I have this version on a different machine) the same database displays everything correctly.
I would like to take this opportunity to thank you very much for a great piece of software!
I really like your product and I've been using it since 2009 :-)
