tar file is the same as other content on the file system or in another

Mouse cursor going missing with SDL [FS#4997]:
|
||||
Under certain circumstances SDL does not notify OpenTTD of changes
|
||||
with respect to the mouse pointer, specifically whether the mouse
|
||||
pointer is within the bounds of OpenTTD or not. For example, if you
|
||||
Alt-tab to another application the mouse cursor will still be shown
|
||||
in OpenTTD, and when you move the mouse outside of the OpenTTD
|
||||
window so the cursor gets hidden, open/move another application on
|
||||
top of the OpenTTD window and then Alt-tab back into OpenTTD the
|
||||
cursor will not be shown.
|
||||
|
||||
We cannot fix this problem as SDL simply does not provide the
|
||||
required information in these corner cases. This is a bug in SDL
|
||||
and as such there is little that we can do about it.
