[solved]Opened projects does nothing lazarus / 9-Editor ---------------------------------------------------------------------- DeroB73 · 2019-12-18 15:40 When i open a project noting is shown, object inspector is empty. No form or code. F12 does nothing. But compiling and running works Right now i can only create new applications.  Lazarus 2.0.6  on Win 10 Any suggestions ? Thx ---------------------------------------------------------------------- lucamar · 2019-12-18 15:48 Have you tried Shift+F12 or Ctrl+F12 to access the list of forms/units? It isn't often but it happens sometimes if you close all the IDE windows (designer & editor) before closing the IDE itself. ---------------------------------------------------------------------- wp · 2019-12-18 15:52 You probably have built the project initially with Lazarus trunk which has a different structure in the xml files. Open the project in trunk again, go to "Project options" > "Miscellanous" and check "Maximize compatibility of project files". After saving you can open the project in Laz 2.0.6. or older. ---------------------------------------------------------------------- DeroB73 · 2019-12-18 17:21 The Shift+F12 or Ctrl+F12 did the trick. it seems i have to do it every time i load a project, but    Thanks lucamar and wp ---------------------------------------------------------------------- lucamar · 2019-12-18 18:03 Quote from: DeroB73 on December 18, 2019, 06:21:15 pmThe Shift+F12 or Ctrl+F12 did the trick. it seems i have to do it every time i load a project, but    That is just a temporal workaround. Fact is you shouldn't have to do it at all, so there's something quite wrong in your system/installation. Unfortunately I don't know what it may be, other than what wp already said ---------------------------------------------------------------------- winni · 2019-12-18 18:46 Hi! No - it is default behaviour: F12   toggle between Form/Editor Ctrl F12 Show Editor Shift F12 Show Form So have a look at the tools if the keymapping did some strange things with F12. Or deleted the entry. Winni
