In the project options, under the Project Files tab, scrolling does not work for the ListIcon "project files" dialog box, nor does the scroll bar in latest version 6.30
By removing #PB_Explorer_FullRowSelect for the listicon id="#GADGET_Project_FileList" In PureBasicIDE\dialogs\Projects.xml,
Seems to solve the problem, but there may be something else with the FullRowSelect flag!
Projects.xml has not changed and it previously worked in version 6.21
