Prior to PHPR6, the 200ms default delay was changed in the file ajaxsuggest.js, which could be changed permanently for all projects/builds by changing it in the Program Files(x86)/PHPRunner5.3/source/include/common folder. We normally change it to 1000 or even 3000ms, because often the popup occurs much too fast and covers your link.
But since PHP6 I can't find the parameter to change, and modifying code for each table after every build and for every project is just not an option. You just have to turn off previews, which is a real shame.
The delay needs to be a global parameter. Has anyone figured out how to set the details previews delay in PHPR6+?
