I am using Alpha 9.2.2 on OS 10.14.6. I was writting a text in TeX mode and it consistently freezes when I reach line 26, column 70. I have to force it closed. It does not seem to matter what I write or if there is text after. I am sending two attachments with screen captures after freezing.
Two more attachements
I confirm that this is a bug. I have experienced it myself recently. This is caused by the percent sign in this line of text which causes an infinite loop when the return key is pressed to insert a new line.
I'll look into this.
Thanks for reporting and sorry for the inconvenience.
This is fixed now.
