Hi, I was using the new Beta version and when right clicking on a column in the folder view I received this error. ![image](https://easyqlik.discoursehosting.net/uploads/db5932/original/1X/8147dc08676faf1b7bb36857865d592eb7ca4440.png) ![image](https://easyqlik.discoursehosting.net/uploads/db5932/original/1X/f81794142c2c3ffc29ed03d640e52091823ea3a1.png) ![image](https://easyqlik.discoursehosting.net/uploads/db5932/original/1X/bc74fe5c76fb22b8f6607e67b9ed89dd87813294.png) Marc ---

Got it. The bug is right-click on column header. Right-click on a row works. I should have this fixed quickly. ---

I’ve posted a 4.0.4 update to fix this error. Make sure you use a fresh browser session so you don’t get a cached copy on the download.
