https://bugs.winehq.org/show_bug.cgi?id=41155 --- Comment #7 from Dan Dascalescu <ddascalescu+wine(a)gmail.com> --- Created attachment 55444 --> https://bugs.winehq.org/attachment.cgi?id=55444 Extra Excel window Installing in a 32-bit prefix avoided the problem of opening that .xlsx file. One note re. the installation instructions: "Note that while the installer will appear to complete successfully in a 64 bit wineprefix, the installed applications will not be usable due to bug 30785." - this is incorrect. The applications are usable, at least as of Wine 1.6.3 and 1.9.16. However, even manipulating *one* Excel file while switching among apps is a major pain, due to #23108 and #41159. After I open a file, there's an extra window that clutters the workspace, while the real window with the spreadsheet gets minimized in the bottom left of the Excel app window. Is this a known problem with MDI support? -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.
