I am encountering an issue with my grid setup. I have a menu on the left side for each item on the grid, and this menu's items change based on the selection in the grid. When the event selection is triggered, an Ajax.request function is called to handle rendering upon successful execution. The problem arises when I click on different rows rapidly or navigate quickly using arrow keys - the grid appears to 'freeze' until the request finishes rendering, even though it registers multiple row clicks and seems to be queuing up consecutive requests. Examining the network activity in the browser debugger shows that the requests are pending, which is unexpected since they are meant to be asynchronous. Is there something I may be missing? Could Ext possibly be handling Ajax requests differently than expected?
