• fix: Windows: ESC won't clear marked occurences after text search in editor
• fix: Windows: in "View computer" dialog copyright doesn't show correct "č" character - encoding problem.

• fix: selected value is white and has white background (invisible)
• fix: Could not open memory image from "all files (.)" filter
• fix: with banking: no memory content is shown in the table (e.g. loaded image)
• fix: in case of banked memory, during load image first ask about memory location, then bank index
• fix: Find sequence dialog does not search by pressing ENTER

8080-cpu:

• fix: CPU is in Stopped state initially. After clicking on "run" it won't and hang whole emuStudio
