#31 Cursor jumps to top of internal editor window when F2 pressed to display graph

[Mark R]

The cursor jumps back to the top of the internal editor window when you press F2 to display the graph.
This is irritating if you are working on a large picture and you want to see how the graph looks.

Steps to replicate.
1. create a signalling chart (or open an existing one) - this may be visible in the other types
2. Create a list of actions with 19 lines. The contents of the lines don't matter providing it draws a valid graph
3. Put the cursor somewhere on line 17
4. Edit the entry to register a change
5. Press F2 to display the revised graph
Note how the cursor has now moved up to line 1

Seriousness:
This is an irritation but if you are updating a large diagram then it could mean extra work because you have to remember the line number you were working on and scroll back down to it.

btw thanks for a really useful tool

Hi Zoltan,

Thanks for responding. Sorry for the delay.

Strange. I am running version 6.3.4
On Windows 10 pro on a 64bit PC with 16GB of RAM.

The attached file can be used to test the problem.
Go to the very last line with text on it – line number 19:
BB->CC:check queue & retrieve message;
Manually insert a space between queue and & so the line looks like this:
BB->CC:check queue & retrieve message;

Press F2 to refresh the picture.
The cursor should have jumped up to the first line.
The attached video shows the problem.

Best regards,
Mark

Hi Mark,

Thanks for reporting this. However, I cannot recreate the bug. For me all the steps you described does not lead to a change in cursor position. A question: do the line numbers (19, for example) have special menaning for you. E.g., do they somehow relate to the window size? I could not replictae the error irrespective of whether the chart with 19 lines fits the window or a scorllbar is needed and whether the scrollbar is at the top, bottom or middle at the time of pressing F2.

What version do you use? What Windows version?

Zoltan
